Objective: To assess fetal visceral adiposity and associated factors during pregnancy. Methods: Secondary analysis of prospective cohort data with 172 pairs (pregnant woman/fetus) treated at public health units. Anthropometric data, metabolic (glucose, glycated hemoglobin, insulin, insulin resistance, total cholesterol and fractions, triglycerides) measures, fetal biometry, and visceral and subcutaneous adiposity in the binomial (pregnant woman/fetus) were evaluated at the 16th, 28th and 36th gestational weeks by ultrasonography. Pearson's correlation coefficient and multiple linear regression were used, with a significance level of 5%. Results: At the 16th week, the mean age of the pregnant women was 26.6 ± 5.8 years and mean weight was 62.7 ± 11.5 kg; 47.0% had normal weight, 28.3% were overweight, 13.3% were underweight, and 11.2% were obese. At 36 weeks, 44.1% had inadequate gestational weight gain, 32.5% had adequate gestational weight gain, and 23.3% had excessive gestational weight gain. Fetal visceral adiposity at week 36 showed a positive correlation with maternal variables: weight (r = 0.15) and body mass index (r = 0.21) at the 16th; with weight (r = 0.19), body mass index (r = 0.24), and gestational weight gain (r = 0.21) at the 28th; and with weight (r = 0.22), body mass index (r = 0.26), and gestational weight gain (r = 0.21) at the 36th week. After multiple linear regression, adiposity at the 28th week remained associated with fetal variables: abdominal circumference (p |
